APPARATUS FOR ROLLING G' MHPMATUS FDH ROLLING GLASS Filed June? 1926 atheetsl-Sh ai;

APRTUS FOR ROLLING GLASS nected to av horizontal suction pipe 19, asindicated in Fig. 4. In the construction illustrated, there are foursuction chambersv 13, each connected to a vertical pipe 18 leading tothe pipe 19 (Fig. 3), the arranvement for exhausting the fair from allof the chambers being the same that' just above described. Similarly,each of the discharge chambers 12 is provided With a laterally anddownwardly extending passage 2O corresponding to the passage 17 andconnected to t e upper ends of the vertical pipes 21 lying alongside thevertical pipes 18 (Fig. 3).

These pipes 21 extend downwardly and laterally intoV a supply pipe 22lying beneath the suction pipe 19 and parallel thereto. A suitablesuction fan is provided for exhausting air from the pipe 19 anda'blower` is connected to the pipe 22 for supplying the -,over thesurface of the roll, thus giving a ,substantial chilling effect, andthere is no esca e of air which might tend to injuriousi ly a ect arts dthe apparatus in the vicinity of tie roll. The discharge from the upperheaders 8, is also directed circumferentially of the upper roll 1, butthe air as thus supplied around the r'oll to the right is permitted todischarge to the air, since this pointis so far removed from the sheet 3that its el'ect -upon such sheet is not harmful.

The arrangement shown in Fi 5 is similar to that of Fig. l except tat inthis construction the headers 23 beneath the roll 2 are arranged fartherto the right so as to give more space at 24 for access to the roll andlip 5 and a baille 25 is provided for giving a. better distribution ofair throu h the header, s indicated by the arrow. The air is Withdrawnthrough the suction chamber 27 as in the other type of construction. Theupper header 26 is also similar to the upper header in the Fig. 1construction with the exception that a baille 28 is employed similar tothe baille 25. Fig. 6 illustrates a modification of the lower header, inwhich two suction chambers 29 and 30 are employed qn opposite sides ofthe discharge chamber 31, and in this construction the outlets 32arearranged vertically instead of at an angle. A pair'of asbestos packingplates 33 and 3i are e1n-` ployed ,bearing against the roll as shown, inorder to prevent leakage at these points. In this construction, the flowof air is circumferential of the roll in both directions e suctionchambers 13, at which' instead of being in the one direction only as inthe Fig. 1 construction. A suitable bl0w-' er is connected to thedischarge chamber,

While the suction chambers are provided with connections leading to asuitable exhaust apparatus.

Tt'hat l claim is: 1. rlhe combination in glass rolling apparatus havinga pair of internally Water coo ed rolls, of supplemental cooling meansfor one `ot' the rolls, comprising a` header extending longitudinallythereof along one side und 4provided with outlet means along ono' sidedirected against the surface of the roll and means Afor supplying agaseous cooling fluid to said header under pressure.

2. The combination in glass rolling a az l ratus, having a pair ofrollsthrough W ich glass is supplied, of coolingfmeans for one of therolls, comprising a header extending along one of the rolls and havinits side hollowed out so asI to t aroun the periphery of the roll, withoutlet means leading through such side, means for supplying gaseouscooling fluid to the header under pressure, a second header at'one sideof the -rst header fitting around the roll and having an inlet openingtoward the rolls and means for app ying suction to such second lheader.

3. The combination in glass rolling aplparatus, having a pair of rollsthrough w ich glass'is supplied, of cooling means for one of the rolls,comprising a header extending along one of the rolls and having its sidehollovved out so as to t around the e riphery of the roll, with outletmeans leading through such side, and inclined obliquely with respect tothe roll, and means for supplying gaseous cooling `fluid to the headerunder pressure to cause a flow thereof through said outlet means andaround the roll in one direction. y

4. The cnbination in glass rolling appa ratus, having a pair of rollsthrough which glass is supplied, of cooling means fori one ofthe rolls,comprising a header extending along one of the rolls and having' itsside` hollovved out so as to t around 'the peripher of the roll withoutlet means leading throng such side, and inclined obliquely withrespect to the roll, means for supplying' gaseous cooling fluid to theheader under pressure to cause a flow thereof through said outlet meansand around the roll in one direction, a second header on the side of thefirst header toward whichthe gaseous fluid from the outlet means isdirected 4fitting around the roll and, having an inlet opening towardthe roll, and means for applying suction to such second header.

5. The combination in glass rolling aplparatus, having atpair of rollsthrough w ch glass is supplie of cooling means for one of the rolls,comprising a header extending along one of the rolls and havin its Isidehollowed out so as to t arounc the -pe riphery oi' the roll, with outletmeans leading through such side, means for supplying gaseous coolingHuid to the header under pressure, Va second header at one side of theirst header fitting around the roll and having an inlet opening towardthe rolls, and means for applying suction to vsuch second header,flexible packing means being provided between the roll Vand the outerside of the second header.

6. The combination in glass rolling aaparatus, having a pair/of rollsthrough winch glass is supplied, of cooling` means for one of the rolls,comprising means for supplying a gaseous Cooling fluid againstvthesurface of the roll and causmg it to iiow circumfering: a headerextending longitudinally of the f' roll and havin@ iis .side hollowedout so as.,

to fit around ttl-ie periphery of .the rollend provided with outletmeans along one side directed against the surface of the roll, and meansfor supplying a gaseous cooling fluid to said header under pressure.
